/etc/hosts completely ignored

[Roberto Nunnari]

Dear Fred,

if I call

-bash-2.05b# host localhost.
localhost has address 127.0.0.1

but that's only because the dns specified in resolv.conf
answers the query with its own 'localhost' entry. Look:

-bash-2.05b# host -d -t A localhost.
;; res_nmkquery(QUERY, localhost, IN, A)
;; res_send()
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 64429
;; flags: rd; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0
;;      localhost, type = A, class = IN
;; Querying server (# 1) address = 195.190.166.166
;; new DG socket
;; got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 64429
;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0
;;      localhost, type = A, class = IN
localhost.              1D IN A         127.0.0.1
rcode = 0 (Success), ancount=1
localhost has address 127.0.0.1


its a remote dns that answers the query.. but naturally it doesn't
know about localhost in a not existant domain as
localhost.noonlights.net that I use for my private network


-bash-2.05b# host -d -t A localhost.noonlights.net.
;; res_nmkquery(QUERY, localhost.noonlights.net, IN, A)
;; res_send()
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 20386
;; flags: rd; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0
;;      localhost.noonlights.net, type = A, class = IN
;; Querying server (# 1) address = 195.190.166.166
;; new DG socket
;; got answer:
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 20386
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0
;;      localhost.noonlights.net, type = A, class = IN
net.                    2D IN SOA       a.gtld-servers.net. 
nstld.verisign-grs.com. (
                                         2003052800      ; serial
                                         30M             ; refresh
                                         15M             ; retry
                                         1W              ; expiry
                                         1D )            ; minimum

rcode = 3 (Non-existent domain), ancount=0
Host not found.


Best regards.
